Climbing rose plant named ‘ORAlodsem’

ABSTRACT

A new variety of Climbing rose suitable for garden decoration, having flowers of burgundy purple striped with cream yellow coloration overlaid with a coral orange blush.

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘ORAlodsem’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Climbing Rose. It has as its seed parent the variety known as ‘ORAstricap’ (not patented) and a non-disseminated seedling of my creation as its pollen parent with the following genetic origin (MEIronsse×HARzazz). It was hybridized by Pierre Orard, Au Jardin des Roses, Etablissements Horticoles Orard, 56 route de Lyon, 69320 Feyzin, France.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combinations of characteristics: its very unusual flowers of burgundy purple striped with cream yellow coloration overlaid with coral orange blush, its many hairs on the peduncle and its very glossy large foliage. The plant has a spreading climbing growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County and Pomona, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘ORAlodsem’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. Dr. Huey (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘ORAstricap’ by the following combination of characteristics: whereas ‘ORAlodsem’ bears double flowers (about 21 to 29 petals) of burgundy purple striped with cream yellow coloration overlaid with a coral orange blush, ‘ORAstricap’ bears semi-double flowers of smoked orange striped cream coloration with Significantly lesser petalage (about 9 to 16 petals). The new variety is classified as a Climbing rose with a spreading climbing growing habit with canes about 300 cm. to about 350 cm. in length, whereas the seed parent is classified as Shrub rose with a significantly shorter growing habit (about 120 to about 150 cm. in height).

The new variety may be distinguished from its pollen parent, a non-disseminated seedling of my creation by the following combination of characteristics: whereas ‘ORAlodsem’ bears double flowers (about 21 to 29 petals) of burgundy purple striped with cream yellow coloration overlaid with a coral orange blush, the non-disseminated seedling bears very double flowers of orange coloration with significantly heavier petalage (about 35 to 40 petals). The new variety is classified as a Climbing rose with a spreading climbing growing habit with canes about 300 cm. to about 350 cm. in length, whereas the pollen parent is classified as a Hybrid Tea rose with a significantly shorter upright growing habit (about 110 cm. in height).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The new variety may be distinguished from its closest commercially available cultivar, ‘MACoranlem’ (U.S. Plant Pat. No. 9,191) by the following combination of characteristics: whereas ‘ORAlodsem’ bears double flowers (about 21 to 29 petals) of burgundy purple striped with cream yellow coloration overlaid with a coral orange blush, ‘MACoranlem’ bears double flowers of striped orange & yellow coloration with significantly heavier petalage (about 32 to 38 petals). The new variety is classified as a Climbing rose with a spreading climbing growing habit with canes about 300 cm. to about 350 cm. in length, whereas the closest commercially available cultivar is classified as a Shrub rose with a spreading significantly shorter growing habit (about 180 to about 250 cm. in height).

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. The branches used for the photograph came from 3 to 4 year-old rose plants of the new variety grown outdoors in Pomona, Calif. in the month of December.

Throughout this specification, color references and/or values are based upon The Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Pomona, Calif. in the month of December. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWER

The new variety sometimes bears its flowers singly, usually in clusters of two to five per stem. Flowers may be borne in regular rounded clusters on strong somewhat short to medium length stems (about 26 to about 60 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a moderate fruity to apple-like fragrance.

BUD

The peduncle is about 3.4 to about 5.1 cm. in length, of somewhat slender caliper (about 0.2 to about 0.3 cm. in diameter), and usually erect. It is smooth with many hairs. Peduncle color is between 146C and 146B often heavily suffused, especially on the side exposed to the sun, with between 187B and 187A.

Before the calyx breaks, the bud is about 1.2 to about 1.5 cm. in diameter at the widest point, about 1.8 to about 2.2 cm. in length, and pointed to somewhat ovoid in shape. The surface of the bud bears between 10 to 12 foliaceous appendages with some stipitate glands and hairs, usually with slender entire foliaceous parts extending beyond the tip of the bud about ¼ or more of its length. Bud color is between 137B and 137A often heavily suffused, especially on the side exposed to the sun, with near 187A.

The sepals are about 2.7 to about 3.4 cm. in length and about 0.8 to about 1.2 cm. in width at the widest point. The outer surface color of the sepal is between 137B and 137A often heavily suffused, especially on the side exposed to the sun, with near 187A. The outer surface of the sepal is moderately rough and bears between 0 to 6 foliaceous appendages with some stipitate glands and hairs. The inner surface color of the sepal is near 146D broadly bordered by near 137B. After the sepals open, the inner surface color is sometimes moderately suffused, especially on the area exposed to the sun, with between 187A and 187B. The inner surface of the sepal is covered with fine wooly tomentum; sepal margins are lined with few stipitate glands and many hairs.

The receptacle of the flower is of moderately long length (about 0.8 to about 1.1 cm.) and average in caliper (about 0.8 to about 1.2 cm. in diameter). The receptacle is cup-shaped in form. Its surface is smooth with thick fleshy walls. The receptacle color is between 144A and 146C often moderately suffused, especially on the side exposed to the sun, with between 187B and 187A.

As the petals open (after the calyx breaks), the bud is about 1.6 to about 1.9 cm. in diameter at the widest point, about 2.0 to about 2.6 cm. in length, and moderately ovoid in form. The color of the under surfaces of the newly opened petals is irregularly striped and flecked with as dark as between 53B and 47A to as light as between 11B and 10B sometimes moderately suffused with between 187C and 53A to as dark as between 187A and 187B. At the point where the petal attaches, there is a large zone of between 1C and 154C. The color of the upper surfaces of the newly opened petals is irregularly striped and flecked with as dark as between 187A and 187B to as light as between 10C and 11B sometimes moderately suffused with between 46B and 45A. At the point where the petal attaches, there is a large zone of between 2B and 1A.

BLOOM

When fully open, the bloom ranges from about 7.4 to about 10.4 cm. in diameter. Petalage is double with about 21 to 29 petals and about 2 to 12 petaloids irregularly arranged. When partially open, the bloom form is moderately high centered to somewhat cupped, and the petals are somewhat tightly spiraled to cupped with petal edges somewhat reflexed outward. When fully open, the bloom form is more cupped, and the petals are loosely cupped to somewhat undulated with petal edges moderately reflexed outward.

PETALS

The substance of the petals is heavy and of moderately thick thickness, with upper surfaces moderately satiny to somewhat velvety and under surfaces slightly shiny.

MALE REPRODUCTIVE ORGANS

Stamens are many in number (average about 155) and are arranged regularly about the pistils; a few are mixed with petaloids or tucked in the calyx. The filaments are of somewhat short to medium length (about 0.6 to about 0.9 cm.) most with anthers. Filaments are between 6A and 7A in color. The anthers are moderately small for the class and all open approximately at the same time. Anther color when immature is near 22A on the external part and near 11D on the internal part. Anther color at maturity is near 163A on the external part and near 200A on the internal part. Pollen is moderate and between 18C and 19C in color.

FEMALE REPRODUCTIVE ORGANS

Pistils vary in number (average about 95). The styles are somewhat uneven, short to average in length (about 0.3 to about 0.7 cm.), moderately heavy in caliper, and loosely bunched to somewhat separated. Stigma color is between 8B and 10B. Style color is near 4D often heavily suffused with between 53A and 53B. Ovaries are usually all enclosed in the calyx.
